What Is a Three-Barrel Curling Iron?

A three-barrel curling iron, also known as a triple barrel waver, is a unique styling tool designed to create beautiful, flowing waves with ease. Unlike traditional curling irons that feature a single rod, a three-barrel iron has three parallel barrels that simultaneously work to craft waves, adding volume and texture to your hair. This design allows you to style larger sections of hair at once, significantly cutting down on styling time.

The benefits of using a three-barrel curling iron are plentiful:

  • Delivers distinct yet flowing waves that look both defined and natural.

  • Accommodates wider sections of hair, reducing overall styling time, ideal for medium to long hair.

  • Allows for consistent waves with less effort than single-barrel irons.

  • Works well on all hair types, from fine to thick, effectively creating lasting waves that enhance your hair's natural movement

When considering the type of three-barrel curling iron to use, you have options such as the deep waver and the regular waver. Both tools are designed to produce wavy styles, but the deep waver offers more pronounced, defined waves due to its deeper grooves. This can be a great choice if you’re looking for a bolder, more dramatic wavy look.

Essential Prep Work Before You Begin

Before you dive into creating those gorgeous waves with your three-barrel curling iron, setting the stage with some essential prep work is crucial for achieving the best results. Proper preparation not only enhances the effectiveness of your styling tool but also helps protect your hair from potential damage.

Start with Clean, Dry Hair:

Ensure your hair is freshly washed and completely dry before styling. Clean hair or second-day hair is best for this hairstyle. It will allow you to create a longer-lasting hairstyle. Additionally, if you are left with moisture in your hair from damp hair, it can lead to heat damage when exposed to high temperatures.

Detangle Thoroughly:

Smooth, tangle-free hair is key to preventing snags and breakage while using the 3 barrel curling iron. Use a wide-tooth comb or a detangling brush to gently remove any knots, starting from the ends and working your way up to the roots.

Apply Heat Protectant:

Never underestimate the importance of a good heat protectant spray. This product creates a protective barrier over the hair shaft, which helps reduce moisture loss and thermal damage during heat styling. Spritz your hair evenly before you start curling.

Section Your Hair:

Divide your hair into manageable sections. Not only does this make the styling process more organized, but it also ensures that each wave is uniform and well-defined. Use hair clips to secure sections out of the way as you work your way around your head.

How to Use a Three-Barrel Curling Iron

Now that you're excited about the effortless waves a triple barrel curling iron can create, let's get down to business! Here's a step-by-step guide to mastering this styling tool and achieving gorgeous waves that suit your hair type and desired look.

Select the Right Heat Setting:

Choose the appropriate heat setting for your hair type to prevent damage and achieve the best results.

  • Fine or Damaged Hair: Start with a lower heat setting (around 300°F) to avoid heat damage.

  • Normal Hair: A medium heat setting (around 350°F) is a good starting point.

  • Thick Hair: You can crank up the heat to a higher setting (around 400°F) for better wave definition, but be sure to use a heat protectant spray beforehand.

Clamp and Style:

Open the clamp of your 3-barrel curling iron and take a 2-3 inch section of hair. Remember, for a more natural wave, avoid clamping too close to the roots (think 2-3 inches away). This creates a more relaxed, undone wave pattern.

When using the iron, hold it vertically for more defined waves. For a softer, more natural wave, angle the iron slightly. This technique allows you to control the wave’s intensity and ensures that your style suits your overall look.

Hold and Set:

The amount of time you hold the iron on your hair can drastically affect the outcome. For deeper, more pronounced waves, hold the iron closed on each section for about 5-8 seconds. If you prefer a gentler wave, reduce the time to 2-4 seconds.

Release and Repeat:

Gently open the clamp and slowly pull the iron down the hair section, releasing the wave. This careful motion helps preserve the shape of the wave and prevents pulling or snagging that can disrupt the curl pattern. Repeat this process throughout your hair, section by section.

Setting and Finishing Your Look

Once you have styled your hair with a three-barrel curling iron, the final touches are crucial for ensuring your waves last and look their best. Here's how to properly set and finish your wavy hairstyle:

Let the Waves Cool:

Allow your waves to cool completely after styling. This step is essential as it helps set the waves and ensures they hold their shape for a longer duration. Avoid brushing or touching the waves too much while they are still warm to prevent them from losing their form.

Gently Separate the Waves:

For a more natural, effortless look, use a wide-tooth comb to gently separate the waves. Alternatively, using your fingers to lightly tousle the hair can also achieve a beautiful, undone wave effect. This technique helps to soften the waves without causing frizz or disrupting the curl pattern.

Apply Finishing Products:

To enhance the texture and longevity of your waves, consider using a finishing product. A light pomade or a texture spray can add definition and control to your style, while a beach wave spray can provide that perfect tousled, beachy look. These products help polish off the waves, making them appear more refined and styled.

  • Ensure the 3 barrel curling iron is heated to the appropriate temperature for your hair type to prevent damage.

  • Apply a heat protectant spray and divide your hair into manageable sections to ensure even styling. 

  • Clamp hair about 2 inches away from the roots to avoid overly tight waves and give a more natural, beachy vibe.

  • Leave out the ends when clamping to keep the style looking soft and natural on short hair.

How To Use a 3 Barrel Curling Iron on Medium Length Hair

Follow these steps to ensure a flawless finish:

  • Set the curling iron to a heat level suitable for your hair type.

  • Apply a heat protectant spray and partition your hair into even sections. 

  • Begin by clamping the iron about an inch away from the roots to avoid excessive volume at the scalp. This placement helps maintain a natural look.

  • For more defined waves, hold the iron on each section for a few seconds longer than usual. Carefully release the clamp and move down the section of hair, avoiding the very ends to prevent heat damage

  • Allow your hair to cool down after curling. This step is crucial as it helps the waves set and last longer.

  • Once cool, gently run your fingers through the waves to separate them for a softer, more natural effect. Apply a light mist of hairspray or a texture spray to add definition and hold to your style.


How To Use a 3 Barrel Waver on Long Hair

Using a three-barrel waver on long hair can create luxurious, flowing waves that are both glamorous and effortless.

Follow these steps to ensure you get the best results:

  • Before you start, ensure your three-barrel waver is heated to the appropriate temperature for your hair type. Long hair, especially if it's thick or treated, may require a higher setting, but it's crucial not to overheat as this can cause damage.

  • Apply a heat protectant spray and divide your long hair into manageable sections.

  • Start from the lower layers of your hair and work your way up. Clamp the waver close to the roots (but not too close to avoid heat damage to the scalp), and hold it for a few seconds before moving down the length of your hair. Repeat this process until all sections are waved.

  • For a defined wave, hold the waver on each section for about 4-6 seconds. If you prefer looser waves, reduce the hold time. After clamping each section, gently release the waver to avoid pulling the hair and distorting the wave pattern.

  • Once all sections are styled, let your hair cool. This helps set the waves. To finish, lightly run your fingers through your hair or use a wide-tooth comb for a more natural look. Avoid brushing vigorously as this can make the waves frizzy.

  • Use a lightweight hairspray or a spray designed for waves to help hold the style in place without weighing down your hair.
